THE  MINERAL  INDUSTRY  OF  CALIFORNIA  IN  1911. 

Fifty-five  out  of  the  fifty-eight  counties  in  California  reported  a 
production  of  one  or  more  of  forty  minerals  during  the  year  1911, 
amounting  to  a  total  value  of  $87,497,879.  This  value,  and  all  others 
mentioned  in  this  Bulletin,  are  for  crude  material  at  the  property. 

The  above  total  as  compared  with  the  1910  output  of  $88,419,079 
shows  an  apparent  decrease  in  1911  of  $921,200.  The  two  amounts  are 
not  strictly  comparable,  however,  because  of  the  fact  that  the  1910  total 
contains  the  value  of  refined  asphalt  produced  during  that  year.  In  the 
1911  figures  this  material,  the  value  of  which  equals  $2,250,000,  has  been 
excluded,  as  no  natural  asphalt  is  produced  in  the  State  and  therefore 
could  not  be  included  without  duplication  of  a  portion  of  the  petroleum 
output.  This  also  applies  to  other  refined  mineral  products,  which 
includes  kerosene,  gasoline  and  other  products  of  the  fractional  distil- 
lation of  crude  petroleum.  Petroleum  is  treated  in  this  report  as  a 
whole,  and  to  add  to  the  output  the  value  of  these  refined  products  would 
be  a  duplication  of  figures,  which  no  matter  how  gratifying  in  swelling 
the  grand  total,  would  be  not  only  misleading,  but  improper. 

As  has  been  the  case  in  recent  years,  petroleum  production  leads  all 
others  by  a  wide  margin,  the  total  output  for  the  year  amounting  to 
84,648,157  barrels,  valued  at  $40,552,088.  Gold  comes  second  with  a 
value  of  $19,738,908.  Cement  ranks  third,  the  total  output  amounting 
to  6,371,369  barrels,  worth  $9,085,625.  Although  greatly  curtailed 
owing  to  smelter-fume  troubles,  copper  holds  fourth  place  on  the  list 
with  a  production  valued  at  $4,604,753.  Other  minerals,  each  with  a 
value  of  over  a  million  dollars,  are  as  follows :  Crushed  rock,  including 
sand  and  gravel,  $3,610,357 ;  brick,  $2,638,121 ;  borax,  $1,456,672. 

It  wiU  be  observed  that  the  increase  in  the  value  of  the  output  of 
cement  was  nearly  $3,300,000  over  that  of  the  previous  year.  It  may 
be  expected  that  the  present  year,  1912,  will  see  this  amount  swelled  to 
a  figure  well  over  $10,000,000.

The  following  pages  treat  in  detail  of  the  production  by  county  as 
well  as  by  mineral.  Some  counties  are  much  larger  producers  of  mineral 
than  others.  Kem  County  for  instance  produced  last  year  more  than 
$20,000,000  worth  of  petroleum,  and  Fresno  County's  oil  production 
exceeded  $9,300,000,  while  that  of  Los  Angeles  was  over  $3,300,000. 
The  largest  copper  producer  was  Shasta  County  with  nearly  $3,700,000, 
and  that  of  Calaveras  County  was  $773,769.  Nine  counties  produced 
the  remainder  of  a  total  of  $4,604,753.

A  glance  at  the  above  tabulated  statement  will  give  the  best  idea  of 
the  relative  production  of  the  various  counties.  It  will  be  observed  that 
out  of  the  fifty-eight  counties  of  the  State  fifty-five  contributed  to  the 
mineral  output  of  1911. 


STATISTICS   STATE   MINING  BUREAU.  9 

The  figures  opposite  ' '  unapportioned "  are  necessary  because  of  the 
fact  that  some  branches  of  the  mineral  industry  are  so  centralized,  that 
if  the  value  of  their  output  were  listed  under  the  county  from  which 
they  come  private  business  would  be  made  public.  For  this  reason 
there  are  several  instances  where  the  real  value  of  the  county  mineral 
yield  is  much  greater  than  is  shown  in  the  above  summary. 

The  omission  of  the  value  of  asphalt  in  the  1911  figures  is  account- 
able for  an  undue  decrease  in  the  case  of  counties  where  oil  refineries 
are  located.  The  figures  for  1910  included  asphalt,  which  was  in  fact  a 
partial  duplication  of  petroleum  value. 

TOTAL  GOLD  PRODUCTION  OF  CALIFORNIA. 

The  following  table  was  compiled  by  Chas.  G.  Yale,  of  the  Division  of 
Mineral  Resources,  U.  S.  Geological  Survey,  but  for  a  number  of  years 
Statistician  of  the  California  State  Mining  Bureau  and  the  U.  S.  Mint  at 
^an  Francisco.  The  authorities  chosen  for  certain  periods  were :  J.  D. 
Whitney,  State  Geologist  of  California;  John  Arthur  Phillips,  author 
of  "Mining  and  Metallurgy  of  Gold  and  Silver"  (1867)  ;  U.  S.  Mining 
Commissioner  R.  W.  Raymond;  U.  S.  Mining  Commissioner  J.  Ross 
Browne;  Wm.  P.  Blake,  Commissioner  from  California  to  the  Paris 
Exposition,  where  he  made  a  report  on  '* Precious  Metals"  (1867)  ;  John 
J.  Valentine,  author  for  many  years  of  the  annual  report  on  Precious 
Metals  published  by  Wells  Fargo  and  Company's  Express;  and  Louis 
A.  Garnett,  in  the  early  days  manager  of  the  San  Francisco  refinery 
where  records  of  gold  receipts  and  shipments  were  kept.  Mr.  Yale 
obtained  other  data  from  the  reports  of  the  Director  of  the  U.  S.  Mint 
and  the  Director  of  the  U.  S.  Geological  Survey.  The  authorities 
referred  to,  who  were  alive  at  the  time  of  the  original  compilation  of  this 
table  in  1894,  were  all  consulted  in  person  or  by  letter  by  Mr.  Yale  with 
reference  to  the  correctness  of  their  published  data,  and  the  final  table 
quoted  was  then  made  up.  The  figures  of  the  last  six  years  are  those 
prepared  for  the  U.  S.  Geological  Survey. 

The  table  shows  that  California  has  produced  a  total  of  about 
$1,548,000,000  in  gold  since  1848.  This  enormous  amount  of  gold  would 
weigh  about  2,580  tons  and  would  require  a  train  of  52  freight  cars,  each 
holding  fifty  tons  of  the  metal.  What  the  ultimate  production  of  gold 
in  California  will  be,  only  the  future  can  tell,  but  at  the  present  the  total 
is  being  swelled  at  the  rate  of  about  $20,000,000  annually,  and  this 
amount  is  likely  to  become  more  rather  than  less,  for  some  years  to  come. 
It  will  be  observed  that  the  largest  production  for  any  one  year  was  in 
1852,  when  it  reached  $81,294,700.  This  was  at  the  time  of  the  most 
active  development  of  the  superficial  placers,  when  thousands  of  men 
were  at  work  with  pan,  rocker,  long-tom  and  sluice,  and  even  the 
hydraulic  method  had  been  introduced  in  a  small  way.

This  Bureau  has  never  independently  collected  statistics  of  gold  and 
silver  output,  but  has  used  totals  and  distribution  by  county,  as  obtained 
from  the  U.  S.  Geological  Survey.  All  gold,  silver,  and  platinum 
figures  in  this  Bulletin  are  derived  from  this  source. 

Petroleum  production  in  California — 1875-1911. 

For  the  early  years  of  petroleum  production  in  California  the  statis- 
tical records  are  rather  incomplete,  especially  as  to  price.  In  Bulletin 
No.  60,  California  State  Mining  Bureau,  the  total  value  of  petroleum 
produced  from  1887  to  1909,  inclusive,  is  given  as  $136,693,228.  Add- 
ing to  this  amount  the  value  of  the  1910.  and  1911  output  gives  a  grand 
total  of  $214,934,858  for  the  value  of  the  petroleum  produced  in  the 
State  during  the  past  twenty-five  years. 

The  following  table  is  of  much  interest  to  all  who  are  engaged  in  the 
production  of  petroleum.  It  was  about  twenty  years  before  the  output 
of  the  entire  State  reached  the  dignity  of  a  million  barrels  annually. 
Within  the  past  ten  years  the  annual  production  has  increased  with 
little  fiuctuation  from  about  14,000,000  barrels  to  over  84,000,000 
barrels  annually.

12  MINERAL    INDUSTRY    OF    CALIFORNIA. 

Antimony. 

Antimony  deposits  have  been  worked  in  a  small  way  in  the  past,  in 
Inyo,  Kern,  Riverside,  and  San  Benito  counties.  No  production  has 
been  reported  since  1901  although  in  the  present  year,  1912,  there  has 
been  some  active  development  work  done  and  a  renewed  output  of  this 
metal  is  looked  for  in  the  near  future.  Antimony  occurs  in  some  other 
localities  than  those  above  mentioned. 

Reference:  Bull.  38:62.     Eighth  Report,  p.  485.     Tenth  Report, 
p.  515.     Eleventh  Report,  p.  371.     Thirteenth  Report,  p.  31. 

Asbestos. 

Deposits  of  asbestos  are  located  in  Amador,  Butte,  El  Dorado,  Fresno, 
Placer,  Riverside,  San  Bernardino,  San  Diego,  Sierra  and  Trinity 
counties.  There  are  surface  indications  of  the  mineral  in  many  other 
counties  but,  to  date,  little  if  any  development  work  has  been  done  upon 
them.  The  actual  production  of  asbestos  in  California  is  very  small, 
the  amount  reported  to  the  State  Mining  Bureau  being  only  125  tons, 
valued  at  $500,  for  1911.  Less  than  10  per  cent  of  the  asbestos  used 
in  the  United  States  is  produced  in  this  country,  and  of  this  amount 
practically  all  is  mined  in  the  Eastern  and  Middle  Western  states.  The 
great  bulk  of  the  raw  product  is  imported  from  Canada  where  a  high 
grade  of  asbestos  of  long  fiber  and  great  tensile  strength  is  produced. 

The  uses  of  this  mineral  are  many  and  constantly  increasing,  and  as 
the  requirements  for  asbestos  in  California  increase  the  industry  will 
in  time  become  an  important  one  in  this  State. 

The  lower  grades,  used  in  fireproof  roofing,  etc.,  bring  a  price  of  about 
$20  per  ton,  and  from  this  figure  the  price  goes  up  as  high  as  $200  per 
ton  for  asbestos  which  is  suitable  for  the  manufacture  of  curtains  and 
tapestries  and  other  fabrics,  as  well  as  for  steam  packing,  friction  facing 
for  brakes,  insulating  tapes,  etc. 

Two  distinct  minerals  are  known  on  the  market  as  asbestos.  One  is 
called  tremolite,  the  other  chrysotile.  These  are  trade  terms.  The  latter 
is  superior  in  strength  and  flexibility. 

For  complete  information  regarding  the  properties  of  this  mineral, 
and  location  of  deposits  in  California,  see  Bulletin  No.  38,  p.  261. 

Asphalt. 

Natural  asphalt  exists  in  small  amount  in  Kern,  Los  Angeles,  Mon- 
terey, San  Luis  Obispo,  Santa  Barbara,  Santa  Clara,  Santa  Cruz,  and 
Ventura  counties.  For  economic  reasons  refined  asphalt,  only,  has  been 
commercially  used  in  the  State  in  recent  years.  In  excess  of  180,000 
tons  of  the  refined  product  were  produced  from  petroleum  in  California 
during  1911,  having  a  value  exceeding  $2,250,000.  These  figures  are 
not  used  in  the  total  mineral  production  of  the  State  because  the  value 


STATISTICS    STATE   MINING   BUREAU.  13 

of  the  crude  petroleum  from  which  it  is  made  has  been  included,  and  the 
addition  of  the  value  of  this  by-product  would  give  an  erroneous  result, 
too  high  by  the  above  amount. 

Oil  refineries  are  situated  in  the  following  counties :  Alameda,  Contra 
Costa,  Fresno,  Kern,  Los  Angeles,  San  Diego,  Santa  Barbara,  San  Luis 
Obispo,  San  Francisco,  and  Ventura. 

California's  production  of  asphalt  in  1911  was  greater  than  the 
entire  amount  imported  into  the  United  States  from  all  foreign  coun- 
tries. It  is  used  principally  in  street  paving;  also  for  roofing,  water- 
proofing, insulating  and  as  a  preservative  for  piling,  etc. 

Ba  ry  tes.  \\ 

Deposits  of  barytes  are  known  in  Butte,  Mariposa,  Shasta,  and  San\  \ 
Bernardino    counties.     Production   in   the    State   for   the   year    1911  ^ 
amounted  to  309  tons  valued  at  $2,207,  or  an  average  value  of  a  little 
more  than  $7  per  ton.     This  is  for  crude  material  at  the  property.     If 
the  product  is  sorted  and  ground  the  average  price  obtained  is  about 
double  the  figure  named. 

Its  principal  uses  are  in  the  paint  industry,  in  the  manufacture  of 
paper  and  rope,  in  the  tanning  of  leather,  and  in  the  refining  of  sugar. 

The  demand  for  barytes  is  increasing. 

Bismuth. 

Bismuth  is  not  abundant  in  California  although  an  important  locality 
has  been  reported,  viz.,  near  the  head  of  Thousand  Palm  Canon  in 
Riverside  County,  about  25  miles  northeasterly  from  Indio,  at  the 
Lang  copper  mine. 

Bituminous  rock. 

San  Luis  Obispo,  Santa  Cruz,  and  Solano  counties  Reported  produc- 
tion of  bituminous  rock  in  1911,  to  the  amount  of  75,125  tons  valued  at

Borax. 

Deposits  of  borax  are  known  in  Inyo,  Kern,  Lake,  Los  Angeles, 
Imperial,  San  Bernardino,  Solano,  Tehama,  and  Ventura  counties.  In 
the  desert  portions  of  the  State  its  occurrence  is  more  or  less  common 
in  the  beds  of  ancient  lakes.  In  other  places  it  is  mined  as  an  ore, 
chiefly  colemanite,  which  occurs  in  vein-like  masses.     The  output  in 


1^  MINERAL   INDUSTRY   OF   CALIFORNIA. 

California,  which  is  the  sole  domestic  source  of  borax,  in  1911  amounted 
to  50,945  tons  valued  at  $1,456,672. 

Cement. 

The  growth  of  the  cement  industry  has  been  one  of  the  noteworthy 
features  of  the  mineral  industry  in  recent  years.  The  first  authentic 
reported  production  of  cement  in  California  was  in  1891  when  5,000 
barrels,  valued  at  $15,000,  represented  the  output.  During  1911  the 
production  was  6,371,369  barrels,  valued  at  $9,085,625,  or  an  increase 
of  918,176  barrels,  and  $1,599,910  in  value  over  the  previous  year,  when 
the  yield  amounted  to  5,453,193  barrels  worth  $7,485,715.  The  great 
and  growing  popularity  of  concrete  buildings  and  other  structures  in 
the  State  is  largely  responsible  for  the  above  remarkable  showing.  In 
value  of  annual  output  cement  is  now  surpassed  only  by  petroleum  and 
gold. 

The  industry,  as  is  the  case  with  one  or  two  others,  is  so  highly  cen- 
tralized that  it  is  impossible  to  apportion  the  production  to  the  counties 
in  which  the  plants  are  located  without  making  private  business  public. 

Chrome. 

Chrome,  or  chromite,  is  produced  in  California  to  a  very  limited  extent 
although  the  deposits  are  the  most  extensive  of  any  in  the  United  States. 
Chrome  has  been  mined  in  the  following  counties :  Alameda,  Calaveras, 
Del  Norte,  Fresno,  Glenn,  Lake,  Placer,  San  Benito,  San  Luis  Obispo,  • 
Shasta,  Siskiyou,  Sonoma,  Tehama,  Trinity,  and  Tuolumne. 

During  1911  the  reported  production  of  chromite  was  as  follows :

Clay  brick. 

Brick  of  every  description  including  clay,  magnesite,  sand  lime,  com- 
mon, pressed  and  glazed,  were  produced  in  California  during  1911  to 
the  amount  of  327,474  M  valued  at  $2,638,121,  as  compared  with 
340,883  M  worth  $2,934,731  manufactured  and  sold  in  1910.  The 
decrease  is  due  to  overproduction  in  1910  as  well  as  to  a  natural  falling 
off  owing  to  the  unprecedented  gain  in  concrete  construction  of  all  kinds. 

Clays  are  abundant  in  many  counties  of  California,  and  large  indus- 
tries have  been  built  up  in  the  manufacture  of  the  great  variety  of  clay 
products.  There  is  less  really  fine  kaolin  than  is  desired.  However,  a 
porcelain  factory  has  been  built  at  Richmond  in  Contra  Costa  County, 
where  this  refined  branch  of  the  clay  industry  is  in  o-  fair  way  to  ])e 
carried  to  success.  ^

Clay — Pottery. 

At  one  time  or  another  pottery  clays  have  been  quarried  in  thirty- 
!  three  different  counties  in  the  State,  from  Siskiyou  in  the  north  to  San 
Diego  in  the  south.  The  production  as  reported  by  operators  for  the 
year  1911  amounted  to  224,576  tons  valued  at  $252,759  as  compared  with 
the  output  of  249,028  tons  worth  $324,099  in  1910.  From  present  indi- 
cations this  falling  off  is  merely  temporary  as  the  first  half  of  1912  has 
seen  the  installation  of  several  new  plants  for  the  handling  of  this 
product  and  the  future  prospects  of  the  industry  are  of  the  brightest.

MINERAL    INDUSTRY    OF    CALIFORNIA. 


Coal. 

Coal  deposits  developed  to  a  greater  or  less  extent  are  found  in  the 
following  counties  of  the  State:  Alameda,  Amador,  Calaveras,  Colusa, 
Contra  Costa,  Del  Norte,  Fresno,  Humboldt,  Kern,  Mendocino,  Modoc, 
Monterey,  Orange,  Riverside,  Sacramento,  San  Benito,  San  Diego,  San 
Luis  Obispo,  Santa  Clara,  Shasta,  Siskiyou,  Sonoma,  Stanislaus,  Sutter, 
and  Trinity.  Actual  production  is  small,  amounting  to  but  11,047 
tons  valued  at  $18,297  during  1911.  Coal  has  been  produced  contin- 
uously in  this  State  since  1861.  Up  to  1903  the  annual  output  varied 
between  100,000  and  200,000  tons.  With  the  advent  of  petroleum  as  a 
fuel  the  coal  production  has  rapidly  dwindled.  "With  one  or  two  excep- 
tions California  coal  is  a  lignite  of  inferior  quality. 

Copper. 

Copper  is  widely  distributed  throughout  the  State,  the  following 
counties  containing  copper  ores :  Alameda,  Alpine,  Amador,  Calaveras, 
Colusa,  Contra  Costa,  Del  Norte,  El  Dorado,  Fresno,  Glenn,  Humboldt, 
Inyo,  Kern,  Lassen,  Los  Angeles,  Madera,  Marin,  Mariposa,  Mendocino, 
Merced,  Mono,  Napa,  Nevada,  Placer,  Plumas,  Riverside,  San  Benito, 
San  Bernardino,  San  Diego,  San  Luis  Obispo,  Santa  Clara,  Shasta, 
Sierra,  Siskiyou,  Sonoma,  Stanislaus,  Sutter,  Tehama,  Trinity,  Tulare, 
Tuolumne,  and  Yuba. 

Eleven  counties  reported  production  for  the  year  1911,  the  total 
amounting  to  36,838,024  pounds  valued  at  $4,604,753,  as  compared  with 
53,721,032  pounds  worth  $6,680,641  in  1910.  The  great  decrease  is  due 
to  the  much  discussed  ''fume"  trouble  between  the  smelters  and  the 
farmers  of  the  various  adjacent  localities,  as  well  as  with  the  govern- 
ment. This  difference,  however,  seems  now  to  be  in  a  fair  way  to  finding 
a  satisfactory  solution.

Crushed  rock. 

Under  this  general  heading  are  included  macadam,  rubble,  trap  rock, 
riprap,  sand  and  gravel.  When  producers  in  their  answers  to  inquiries 
have  stated  the  use  to  which  their  rock  was  put  the  classification  has 


STATISTICS   STATE   MINING   BUREAU. 


ir 


been  made  accordingly.  In  a  large  number  of  cases,  however,  it  is 
absolutely  impossible  for  the  producer  himself  to  know  how  much  of 
his  output  has  been  used  in  street  work,  how  much  in  concrete  con- 
struction, etc.,  and  a  tabulation  of  ** Crushed  Rock— Unclassified"  has 
been  made  to  cover  such  instances.  The  total  crushed  rock  figures  here 
given  are  comparable  with  the  sum  of  the  macadam  and  rubble  figures 
as  found  in  previous  bureau  publications. 

During  1911  crushed  rock  was  produced  in  California  to  the  amount 
of  6,487,223  tons,  having  a  value  at  the  quarry  of  $3,610,357.  This  is  a 
marked  increase  over  the  1910  output,  which  totaled  5,827,828  tons 
valued  at  $2,777,690.  Values  of  this  class  of  material  are-  far  from 
uniform.  Accessibility  of  the  deposit,  quality  of  the  rock,  labor  con- 
ditions, etc.,  make  each  local  case  a  separate  and  distinct  one. 

Thirty-three  counties  reported  production  of  crushed  rock  in  1911. 
Without  doubt  the  actual  output  is  in  excess  of  the  figures  given  owing 
to  the  nature  of  the  industry,  and  producers  who  have  not  received 
inquiries  from  the  State  Mining  Bureau  will  do  the  State  and  their 
county  a  service  if  they  will  forward  their  names  and  addresses  to  the 
Statistician,  California  State  Mining  Bureau,  Ferry  Building,  San 
Francisco,  Cal. 

Crushed  rock  is  used  for  so  many  purposes  that  it  is  very  difficult 
to  properly  segregate  the  amounts  produced  into  the  proper  places. 
Among  the  uses  of  crushed  rock  are  concrete  for  buildings,  for  walls, 
sidewalks  and  in  machinery  foundations.  Also  for  macadamizing 
streets  and  for  other  uses.  The  larger  rocks,  used  for  filling  embank- 
ments, building  breakwaters  and  for  similar  uses  are  not  included  in 
crushed  rock. 

Following  are  given  county  figures  for  the  various  branches  of  the 
crushed  rock  industry  as  far  as  possible,  as  well  as  total  figures  covering 
the  industry  as  a  whole :

20  MINEKAL   INDUSTRY   OF    CALIFORNIA. 

Feldspar. 

The  feldspars  occur  as  constituents  of  nearly  all  rocks.  The  feldspar 
of  commerce,  however,  is  all  obtained  from  pegmatites,  where  the  crys- 
tals are  large  enough  to  admit  of  more  or  less  sorting.  The  better  grades 
of  feldspar  are  used  in  pottery  manufacture  and  in  the  making  of 
various  enamel  wares.  Where  a  high  per  cent  of  impurities  is  present 
the  material  is  ground  coarsely  and  used  in  the  manufacture  of  * '  ready 
roofing,"  ''chicken  grit,"  etc.  Small  quantities  are  used  in  glass 
making,  and  as  an  abrasive  in  scouring  soap.  Attempts  have  been 
made  to  prove  the  value  of  the  potash  feldspars  as  fertilizer. 

Feldspar  was  first  produced  commercially  in  California  in  1910. 
During  1911,  740  tons  were  quarried  and  sold,  the  crude  material  at  the 
property  having  a  value  of  $4,560,  or  an  average  of  a  little  more  than 
$6  per  ton. 

Fuller's  earth. 

Fuller's  earth,  so  named  from  its  earliest  use  in  fulling  wool,  is  a 
rather  rare,  soft,  friable  rock  whose  value  depends  altogether  on  its  tex- 
ture and  its  filtering  and  absorbent  properties.  It  has  no  definite  com- 
position, mineralogically,  its  physical  properties  rather  than  a  chemical 
analysis  determining  its  commercial  value.  Fuller's  earth  was  first 
produced  in  the  United  States  in  the  early  nineties,  and  has  been  mined 
and  marketed  in  a  small  way  in  California  annually  since  1899.  During 
1911  the  output  amounted  to  466  tons  valued  at  $5,294,  an  average  spot 
value  of  $11.36  per  ton. 

Reference:  Bull.  38,  p.  273. 

Gems. 

The  following  named  gems  are  among  those  commonly  produced  in 
California:  Agate,  amazonstone,  almandine,  beach  stones  of  many  kinds, 
benitoite,  bloodstone,  chalcedony,  californite,  chrysoprase,  datolite,  dia- 
mond, fossil  coral,  garnet,  hyacinth,  hiddenite,  jasper,  kunzite,  moon- 
stone, rose,  smoky  and  gold  quartz,  rhodolite,  rhodonite,  rock  crystal, 
spodumene,  sunstone,  topaz,  tourmaline,  turquoise,  turquoise-matrix, 
and  many  other  stones  with  trade  names. 

The  following  counties  reported  production  of  one  or  more  of  the 
above :  Butte,  Fresno,  Inyo,  Los  Angeles,  Riverside,  San  Diego,  Siskiyou, 
and  Tulare. 

New  deposits  of  gems  are  continually  being  discovered.  The  value  of 
the  stones  in  the  rough  is  extremely  problematical,  and  the  demand  is 
more  unsteady  than  for  the  "precious"  stones,  hence  spot  values  of  the 
crude  material  are  difficult  to  arrive  at.  The  figures  here  given  are  the 
result  of  (1)  correspondence  with  producers,  and  (2)  obtaining  esti- 
mates from  dealers  and  others  who  are  actively  engaged  in  the  business,  | 
and  the  result  is  the  closest  approximation  that  can  be  deduced.     There 


STATISTICS   STATE   MINING   BUREAU.  21 

was  an  overproduction  of  gems  in  1910  and  as  a  result  the  1911  output 
is  somewhat  below  normal. 

A  large  number  of  beach  stones  of  every  description  were  utilized  as 
gems  in  Los  Angeles  County  during  the  year.  This  branch  of  the  indus- 
try did  not  show  a  decrease,  the  local  demand  in  Los  Angeles  City  and 
the  surrounding  beach  towns  being  quite  strong. 

Small  diamonds  of  good  quality  continue  to  be  occasionally  found  in 
Butte  County,  and  development  work  along  these  lines  is  to  be  vigor- 
ously pushed  in  the  near  future,  according  to  parties  interested. 

Rhodonite  and  californite  exist  in  considerable  amount  in  Fresno 
County  although  the  output  was  very  small  during  the  past  year. 

Several  discoveries  were  made  in  Inyo  County  in  1911.  The  actual 
output  was  almost  nothing  but  the  outlook  is  for  an  increase  in  this 
branch  of  the  mineral  industry  in  the  near  future  as  the  stones  are  of 
the  highest  quality. 

Gem  mines  of  as  yet  undetermined  value  are  located  in  San  Benito 
County,  and  various  deposits  in  Riverside  County  are  likely  to  become 
large  producers  with  further  development.  San  Bernardino  produced 
no  gems  during  the  year  1911  although  two  especially  well  equipped 
anpanies  are  doing  preliminary  work  and  expect  to  place  their  output 
on  the  market  before  the  end  of  1912. 

San  Diego  County  contains  more  gem  deposits,  developed  and  unde- 
A  eloped,  than  any  other  section  of  the  State.  Its  annual  output  has 
])een  estimated  to  be  as  high  as  $100,000.  The  value  of  the  cut  stones 
would  doubtless  reach  that  figure,  although  an  investigation  of  condi- 
tions there  has  proved  that  the  overproduction  of  1910  is  still  affecting 
the  industry — almost  a  year  and  a  half  later — both  as  concerns  produc- 
tion and  price,  and  one  quarter  of  the  above  figure  represents  a  fair 
average  estimate  of  the  value  of  the  crude  gem  material  mined  in  the 
county  during  1911. 

In  Siskiyou  and  Tulare  counties  the  same  general  conditions  prevail, 
and  at  present  there  is  no  doubt  but  that  demand  and  prices  offered  are 
not  keeping  pace  with  possible  production.

Granite. 

Granite,  used  as  a  building  stone  as  well  as  for  monumental  and  other 
purposes,  was  produced  in  California  during  1911  to  the  amount  of 
401,209  cubic  feet  and  value  of  $344,351,  crude  stone  at  the  property. 
Stone  used  for  curbing  is  hereby  listed  separately,  the  total  value, 
including  curbing,  being  $355,742. 

California  granite  has  no  superior  in  the  world.  The  past  few  years 
has  seen  some  of  the  most  beautiful  and  classical  buildings  in  the  work] 
constructed  in  this  State  from  California  granite.  Among  these  are 
several  banking  buildings  and  the  Postoffice  and  Customs  House  in  San 
Francisco,  also  several  very  beautiful  buildings  on  the  campus  of  the 
University  of  California.  This  granite  is  obtained  from  quarries  in 
a  number  of  counties,  among  which  there  seems  little  choice,  as  to 
superiority.

Graphite. 

No  natural  graphite  was  produced  in  California  during  1911  although 
there  are  deposits  of  the  mineral  located  in  several  counties  in  the  State, 
and  the  owners  of  one  property  reported  development  work  having  been 
done  in  the  course  of  the  year  with  a  possible  output  for  1912.  Graphite 
deposits  have  been  discovered,  and  exploited  to  some  extent,  in  the 
following  counties:  Fresno,  Los  Angeles.  ]\rendocino,  San  Bernardino, 
Siskiyou,  Sonoma,  and  Tuolumne. 

The  demand  for  graphite  shows  a  steady  increase.  Imports,  largely 
from  Mexico  and  Ceylon,  amount  to  about  $2,000,000  annually.  On 
account  of  its  infusibility  and  resistance  to  action  of  molten  metals, 
graphite  is  very  valuable  in  the  manufacture  of  crucibles;  it  is  also 
largely  used  in  the  manufacture  of  electrical  appliances,  as  a  steam 
packing,  as  a  lubricant,  in  manufacture  of  paint  and  lead  pencils,  and 
in  many  other  ways.  Prices  obtainable  vary  widely,  depending  upon  the 
grade  of  the  product,  and  upon  its  being  amorphous  or  crystalline.  The 
lowest  grades  bring  about  $10  per  ton,  and  from  this  figure  prices  range 
up  as  high  as  $200  for  the  pure  crystalline  variety. 

A  few  years  ago  only  crystalline  graphite  of  superior  quality  could  be 
used  in  many  of  the  arts  and  manufactures.  Now  inferior  mineral 
may  be  concentrated  by  flotation,  but  the  discovery  that  a  fair  grade  of 
graphite  could  be  manufactured  from  a  good  grade  of  coal  has  seriously 
hurt  the  mining  of  graphite,  and  lowered  the  price  so  that  inferior 
mineral  scarcely  finds  a  sale,  or  can  be  concentrated  at  a  profit.

Infusorial  earth. 

Infusorial  earth,  also  known  as  diatomaceous  earth,  tripoli  and  trip- 
olite,  occurs  in  California  very  extensively.  Deposits  of  importance  are 
located  in  Los  Angeles,  Monterey,  Orange,  San  Benito,  San  Bernardino, 
San  Luis  Obispo,  Santa  Barbara,  Shasta,  and  Tehama  counties. 

The  production  for  1911  amounted  to  2,194  tons  valued  at  $19,670 
as  compared  with  1,843  tons  valued  at  $17,617  quarried  and  sold  during

Iron  ore. 

Iron  deposits  of  great  extent  are  known  to  exist  in  thirty-one  different 
counties  of  the  State.  For  various  economic  reasons  the  iron  industry 
has  made  little  progress  to  date.  The  future  possibilities  along  these 
lines  are  very  great.  Actual  production  of  iron  ore  in  1911  amounted 
to  558  tons  valued  at  $558,  compared  with  570  tons  in  1910,  valued  at 
$900.

Lime  and  limestone. 

Fourteen  counties  in  the  State  reported  a  production  of  lime  or 
limestone,  or  both,  for  the  year  1911.  Several  kilns  were  closed,  during 
the  year,  for  one  reason  or  another.  The  average  price  of  lime  per 
barrel  was  seven  per  cent  lower  than  during  the  previous  year.  Lime- 
stone production  also  decreased  in  amount  and  value,  owing  in  part  to 
the  curtailment  of  the  copper  industry  and  the  consequent  lessened 
demand  for  limestone  as  flux.  A  considerable  tonnage  of  limestone  was 
used  in  road  building  during  the  year,  and  has  been  classified  as 
macadam.     This  fact  makes  a  possible  apparent  decrease. 

The  total  lime  production  was  429,587  barrels,  valued  at  $390,988  as 
compared  with  an  output  of  479,507  barrels  valued  at  $477,683  in  1910. 
Limestone  to  the  amount  of  516,398  tons  was  quarried  and  used  as  such, 
and  had  a  spot  value  of  $452,790  as  compared  with  684,635  tons  valued 
at  $581,208  for  the  previous  year.

Magnesite. 

Occurrences  of  magnesite  are  known  in  Alameda,  Fresno,  Mendocino, 
Napa,  Placer,  San  Benito,  Santa  Clara,  Riverside,  Stanislaus,  Sonoma, 
Tulare,  and  other  counties  in  California. 

Magnesite  is  used  in  the  manufacture  of  paper,  in  making  refractory- 
brick  and  what  is  known  as  magnesite  flooring,  and  in  the  manufacture 
of  carbon  dioxide,  principally.  California  is  the  only  State  in  the 
Union  that  produces  this  mineral.

Manganese. 

Manganese  is  found  in  the  following  counties  of  this  State:  Alameda. 
Colusa,  Merced,  Placer,  Plumas,  Riverside,  San  Benito,  San  Joariuiii. 
San  Luis  Obispo,  Santa  Clara,  and  Sonoma. 

Production  has  been  reported  in  the  State  almost  continuously  for  the 
past  twenty-five  years  amounting  to  9,254  tons  valued  at  $87,910  for  the 
quarter  century.  The  great  bulk  of  this  output  is  credited  to  the  first 
half  of  that  period.  Since  1903  the  production  has  been  nominal.  In 
1911  two  tons  with  a  spot  value  of  $40  represent  the  average  for  several 
years. 

Marble. 

Only  three  counties  reported  a  production  of  marble  during  1911 
although  large  deposits  of  the  finest  marble  exist  very  extensively 
throughout  the  State,  and  will  most  certainly  in  time  take  the  place  of 
the  eastern  and  foreign  stone,  which  is  annually  used  for  building  and 
ornamental  purposes.

Mineral  paint. 

Butte,  Calaveras,  Los  Angeles,  Napa,  Nevada,  Placer,  Riverside,  Siski- 
you, Sonoma,  Stanislaus,  Trinity,  and  Yuba  counties  contain  extensive 
deposits  of  mineral  paint.  The  first  production  of  this  material  reported 
in  California  was  in  1890.     Since  that  date  there  has  been  an  annual 

I  output  of  from  100  to  600  tons  roughly. 
i  For  1911  a  total  of  186  tons  valued  at  $1,184  was  produced  in  Placer 
and  Stanislaus  counties,  very  nearly  an  equal  amount  in  each. 

Mineral  water. 

California  is  rich  in  her  possession  of  mineral  springs  of  every  kind. 
Figures  published  in  this  report  are  for  mineral  water  actually  bottled 
and  sold.  Millions  of  gallons  are  otherwise  utilized,  or  annually  run  to 
waste,  of  which  no  reliable  data  can  be  compiled.  There  is  a  great 
variance  in  prices  obtained  because  of  the  great  difference  in  the  con- 
stituent ingredients  of  the  several  waters,  and  in  the  consequent  demand 
for  same. 

Returns  from  the  producers  show  the  amount  of  mineral  water  mar- 
keted in  1911  to  have  been  2,637,669  gallons,  valued  at  $590,654,  as  com- 
pared with  2,335,259  gallons  worth  $522,009  in  1910,  an  increase  of 
302,410  gallons,  in  amount,  and  $68,645  in  value.

28  MINERAL    INDUSTRY    OF    CALIFORNIA. 

Natural  gas. 

As  in  the  case  of  mineral  water,  untold  quantities  of  natural  gas  are 
annually  wasted.  Definite  figures  as  to  amount  actually  utilized  are 
difficult  to  arrive  at  as  in  many  cases  the  owners  of  gas  wells  make  no 
attempt  to  measure  the  output,  and  even  the  value  of  the  product  which 
is  used  becomes  a  matter  of  estimate.  This  does  not  hold  in  all  cases,  but 
it  is  true  to  such  an  extent  as  to  make  an  estimate  of  amount  valueless. 
Active  steps  are  now  being  taken  to  conserve  the  vast  supply  of  natural 
gas  in  the  State  and  the  near  future  will  show  an  enormous  increase  in 
value  of  this  branch  of  the  mineral  industry. 

Natural  gas,  used  for  fuel  in  the  oil  fields,  for  lighting  and  for  all 
other  purposes  in  California  during  1911  had  a  value  of  $491,859  as  com- 
pared with  the  1910  consumption  worth  $476,697  (the  latter  figure  taken 
from  "Mineral  Resources  of  the  United  States"  1910,  Part  II,  page  323, 
U.  S.  Geological  Survey).

Onyx  and  travertine. 

Onyx  and  travertine  marble  were  produced  in  California  to  the  value 
of  $91,400  between  the  years  1887  and  1896.  During  the  past  fifteen 
years  there  has  been  no  production  of  this  kind  of  building  stone  in  the 
State,  although  many  partially  exploited  deposits  exist  in  a  score  of 
counties.  Practically  all  the  onyx  and  travertine  now  used  on  the  coast 
are  imported  from  Mexico. 

Paving  blocks. 

Six  counties  reported  production  of  paving  blocks  for  1911  to  the 
amount  of  4,141  M ;  spot  value,  $210,819.  This  is  a  slight  decrease  in 
amount  and.an  increase  in  value  over  the  1910  production,  which  equaled 
4,434  M  in  number  with  a  value  of  $198,916.  Paving  blocks  are  mostly 
made  from  granite  or  andesite,  the  latter  variety  being  known  to  the 
trade  as  '  *  basalt  blocks. ' '  Solano  and  Sonoma  are  the  largest  producers 
of  this  class  of  blocks.

Platinum. 

Platinum  production  in  California  during  the  year  1911  amounted  to 
511  Troy  ounces,  valued  at  $14,873,  as  compared  to  337  ounces  worth 
$8,386  in  1910.  Platinum  yield  in  the  State  is  largely  due  to  its  inci- 
dental recovery  along  with  placer  gold  in  various  dredging  and 
hydraulic  fields. 

Pyrite. 

Pyrite  production  in  California  for  1911  amounted  to  54,225  tons,, 
valued  at  $182,954,  as  compared  with  42,621  tons  worth  $179,862  during^ 
1910.  These  figures  include  only  pyrite  actually  used  in  the  manufac- 
ture of  sulphuric  acid.  Many  thousand  tons  of  pyritic  ores  are  annually 
treated  in  the  State  in  which  the  sulphur  content  is  not  utilized,  the 
fumes  passing  out  into  the  air.  Strenuous  efforts  are  being  made,  how- 
ever, to  render  these  noxious  fumes  harmless  to  the  vegetation  of  the 
surrounding  regions.

Quicksilver. 

Contrary  to  predictions  generally  made  at  the  end  of  the  year  the 
quicksilver  output  for  1911  showed  a  considerable  increase  over  that  ol' 
1910.  The  production  for  1911  was  19,109  flasks  valued  at  $879,205,  in 
flasks  of  75  pounds  at  $46.01  per  flask,  which  was  the  average  price 
received  in  the  San  Francisco  market  during  the  year.  This  is  an 
increase  in  quantity  of  1,444  flasks,  and  in  value,  of  $80,203  over  the 
production  of  1910. 

The  largest  output  came  from  San  Benito  County,  followed  by  Sant;i 
Clara,  Lake,  San  Luis  Obispo,  Napa,  Sonoma,  Santa  Barbara,  Trinity, 
and  Colusa  counties  in  the  order  named. 

The  following  counties  also  contain  quicksilver  deposits,  some  of 
which  promise  to  become  producers  at  an  early  date :  Kings,  Monterey. 
El  Dorado,  Fresno,  Shasta,  Solano,  Stanislaus,  and  Yolo.  Unusual 
activity  has  been  apparent  among  operators  and  owners  of  quicksilver 
mines  during  1911  and  the  outlook  for  a  further  increase  in  the  futuiv 
is  favorable. 

The  1911  quicksilver  production  has  not  been  exceeded  since  190r> 
w^hen  the  product  was  sold  for  $886,081.  The  value  for  succeeding  years

One  of  the  most  important  factors  in  the  increased  output  of  quick 
silver  is  the  advance  in  the  price  of  the  metal.  The  lowering  of  tli* 
cost  of  production  has  also  made  it  possible  to  profitably  treat  a  decreas 
ingly  lower  grade  of  ore,  so  that  now,  a  quicksilver  property  with 
good-sized  vein  of  ore  containing  only  one  half  of  one  per  cent  ol 
mercury  will  pay  expenses,  and  under  the  most  favorable  circumstanci^ 
may  yeild  a  profit.  Quicksilver  is  produced  in  Texas  and  also  is  known 
to  occur  in  several  other  Western  States,  but  California  is  the  greatest 
producer  in  America.  Notwithstanding  this,  the  mines  of  Europe 
control  the  market  and  fix  the  price.

Salt. 

The  California  salt  output  comes  from  two  sources ;  from  the  waters 
of  the  Pacific  Ocean  by  evaporation,  this  branch  of  the  industry  being 
carried  on  principally  on  the  shores  of  San  Francisco  Bay,  as  well 
as  at  Long  Beach  and  San  Diego;  and  in  the  second  case  from  the  old 
lake  beds  in  the  desert  portions  of  the  State,  where  many  thousand 
acres  of  saline  deposits  exist.  South  of  Danby,  in  San  Bernardino 
County,  is  a  large  bed  of  rock  salt  that  has  been  mined  quite  extensively 
at  various  periods  for  many  years  past. 

During  1911  six  counties  reported  a  production  of  173,332  tons  of 
crude  salt  valued  at  $324,255,  or  an  average  of  $1.87  a  ton,  spot  value. 
As  compared  with  the  1910  figures,  when  174,920  tons  were  produced, 
worth  $395,417,  the  output  is  seen  to  be  practically  unchanged  although 
the  price  received  suffered  a  decrease  of  $.41  per  ton.

Both  glass  sand  and  quartz  sand  are  produced  in  small  quantities  in 
California,  possible  production  being  far  greater  than  any  yet  actually 
attained.  During  1911  no  output  of  "Quartz  Sand"  was  reported, 
glass  sand,  however,  being  produced  to  the  amount  of  8,620  tons,  valued 
at  $8,672 — amount  and  value  being  practically  the  same  as  for  the  pre-

Soda. 

Deposits  of  soda  are  located  in  various  parts  of  southern  California, 
more  especially  in  Inyo,  San  Bernardino,  and  San  Luis  Obispo  counties. 
The  1911  production  amounted  to  9,023  tons,  valued  at  $52,887,  as  com- 
pared with  an  output  of  8,125  tons  worth  $11,862  in  1910. 

Tungsten. 

The  value  of  tungsten  produced  in  California  in  1911  amounted  to 
$127,706  as  compared  to  $208,245  in  1910.  Tungsten  is  used  largely  in 
the  steel  industry.  The  ores  are  sold  per  unit  of  tungstic  trioxide,  ores 
of  a  lower  grade  than  45  per  cent  WO3  are  not  generally  marketable. 

Zinc. 

A  small  quantity  of  zinc  was  produced  in  the  State  during  the  years 
1906,  1907,  1908  having  a  total  value  of  $26,708.  With  that  exception 
1911  shows  the  first  returns  from  what  bids  fair  to  become  a  large  indus- 
try. Deposits  of  zinc  ore  exist  in  Inyo,  Orange,  San  Bernardino,  and 
Shasta  counties.  Zinc  occurs  to  some  extent  in  the  ores  of  many  other 
counties  although  as  yet  they  have  not  come  to  be  considered  zinc  ore. 
The  output  for  1911  was  2,679,842  pounds,  valued  at  $152,751. 

In  addition  to  the  foregoing  minerals  eight  others  have  been  produced 
in  the  State  at  different  times,  any  and  all  of  which  may  become  a  factor 
in  the  mineral  output  of  California,  to  wit:  Lithia  mica,  mica,  quartz 
crystals,  serpentine,  slate,  soapstone,  sulphur  and  tin. 

From  1899  to  1905  lithia  mica  was  produced  to  the  total  value  of 
$127,556,  the  output  coming  almost  entirely  from  San  Diego  County. 
The  mineral  was  used  as  a  source  of  lithia,  which  in  the  form  of  the  car- 
bonate is  used  in  the  manufacture  of  effervescing  lithia  tablets,  and  in 
the  preparation  of  mineral  waters,  and  in  the  form  of  the  nitrate  in  the 
making  of  the  "red  fire"  of  pyrotechnics. 

In  1902,  1903,  and  1904  mica  production  to  the  total  amount  of  150 
tons  valued  at  $9,300  was  reported  to  the  State  Mining  Bureau. 

At  various  times  during  the  past  fifteen  years  small  amounts  of  quartz 
crystals  have  been  marketed  in  the  State.  The  total  value  recorded 
being  $57,468.  No  commercial  production  has  been  reported  during  the 
past  three  years. 

Serpentine  has  been  quarried  both  as  a  building  and  as  an  ornamental 
stone  in  various  parts  of  California  during  the  past  twenty  years.  In 
most  cases,  however,  it  lacks  sufficient  brightness  of  color  to  be  desirable 
for  ornamental  purposes,  and  has  too  many  cracks  and  impurities  to 
make  a  first-class  building  stone.  The  value  of  all  the  serpentine  pro- 
duced in  the  State  amounts  to  only  $33,259.  Production  was  last 
reported  in  1907. 

Slate  production  in  California  had  its  beginning  in  1889  and  has  been 
continuous,  in  greater  or  less  amount,  up  to  1911,  when  no  production 


34  MINEKAL    INDUSTRY    OF    CALIFORNIA. 

was  reported.  The  output  has  been  rapidly  declining  in  recent  years. 
Many  large  deposits  of  slate  are  known  in  the  State,  but  its  greatest  use 
in  the  past  has  been  as  a  fireproof  roofing,  and  the  various  brands  of 
* '  Eeady  Roofing ' '  which  have  been  placed  on  the  market  in  recent  years 
have  hurt  the  industry  seriously. 

Soapstone  deposits  of  great  extent  are  located  in  various  parts  of  the 
State  although  none  of  them  have  been  developed  to  any  extent.  The 
first  reported  production  was  in  1893.  Intermittently  since  that  time  up 
to  and  including  the  year  1910,  soapstone  to  the  value  of  $41,559  has 
been  placed  on  the  market.  During  1911  no  output  was  reported  to  this 
Bureau. 

In  several  localities  it  is  possible  to  distill  sulphur  from  the  rocks 
which  are  found  in  limited  areas.  In  the  northern  portion  of  the  State 
are  also  known  springs  which  deposit  sulphur  from  solution.  In  1898  a 
production  of  two  tons  of  sulphur,  valued  at  $50,  was  reported.  No 
other  output  of  sulphur  has  been  recorded  to  date.  In  the  vicinity  of 
Lassen  Peaks  are  several  fumeroles  where  sulphur  is  being  constantly 
deposited  from  vents.  One  of  these  is  known  as  Supan's  Springs,  and 
is  situated  about  five  miles  north  of  Morgan  station;  another  is  called 
Hot  Spring  Valley,  and  is  on  a  tributary  of  Warner  Creek.  Here  are 
scores  of  vents  where  sulphur  is  being  deposited.  A  third  locality  is 
called  Bumpass'  Hell.  This  latter  is  close  to  the  base  of  the  main 
peak  on  its  southern  side.  In  each  of  these  localities  sulphur  occurs, 
but  in  each  instance  it  is  mixed  with  much  earthy  matter  which  reduces 
its  value  materially.  It  is  not  likely  that  any  of  these  deposits  have  a 
present  value  owing  to  the  lack  of  cheap  transportation  facilities.  1 

Tin  was  produced  in  California  in  1891  and  1892  to  the  value  of 
$59,964.  No  other  production  is  known  in  the  history  of  the  State. 
The  deposits  of  tin  ore  are  in  Riverside  County,  seven  miles  east  of 
Corona. 

It  may  not  be  generally  known,  but  petroleum  was  produced  in  a 
small  way  in  California  very  early  in  the  history  of  the  country,  in 
fact,  long  before  it  was  invaded  by  the  army  of  gold  seekers.  Mr.  C. 
]\rorrell,  a  druggist  in  San  Francisco,  is  commonly  credited  with  being 
the  first  to  attempt  the  distillation  of  kerosene  from  crude  petroleum. 
This  was  in  1857,  but  several  years  prior  to  that  Andreas  Pico  made 
illuminating  oil  from  petroleum  which  he  obtained  in  the  Newhall 
region  in  Los  Angeles  County.  This  oil  was  burned,  so  it  is  said,  in 
lamps  in  the  Mission  San  Fernando.  There  is  no  doubt  whatever 
that  the  Spanish  padres  who  built  the  missions  in  California  in  the 
latter  part  of  the  eighteenth  century,  were  aware  of  the  existence  of 
petroleum  here  and  made  use  of  the  brea,  as  the  seepages  are  called.
